To all 'whom t may concern: Y

Be it lmown that I, JOHN PEAnsoN, a j citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and luseful Improvement in Oil Burners, of which thev following is a full, clear, and exact descrip-V tion. f l. My invention relates to improvements in oil burners, and .more particularly to that type of oil burnerfwhich is adapted to heat a furnace, and it consists in the combinations, constructions, and arrangements here- Y in describedandclaimed. Y v

An object of my inventionis to provide an oil burner which operates noiselessly.; f

A further objectof my invention is to provide a device of the type described which has an automatic valve of novel construction.

A lfurther object of my invention is to provide a device of the type described which has a burner ofl novel construction.- Y

A further object of -my invention is to provide a device of the type described which is simple in construction, consists of few moving parts, and is-not likely to easily get out` of order. v Y

Qther objects and advantages will appear. in the following specification, and the novel features of the invention will'be particularly pointed out in the appended claims.

My invention is illustrated inthe accompanying drawings, forming. part of this application', in which-` Figure 1 is a side elevation of the device, portions thereof bein shown in section,

Figure 2 is an andr elevation of the device, tion, and

Figure 3 is an enlarged sectional view of the oil burner.

In carrying out my invention, I' provide a stand or support 1 which has a pedestal 2V integral therewith. On the pedestal 2 I mount a fan 3 vwhich is -preferably of the centrifugal type. The fan 3 is connected by means of a coupling 4 to a valve 5, which will now be described.

The valve 5 comprises a body portion 6 which has a bore 7 adapted to communicate with the fan 3 and a bore 8 which extends at right angles to thevbore 7. Slidably disposed in the bore8 is a valve 9 which has a stem 10 integral therewith, the stem projecting above the body portion 5.

A b by means ofl a pipe 23. Thel burneris'pro` vided `witha casing 24 which is disposedcon` centrically with respect togan adjustable air pipe 25. As will 'be noted in Figure 3, the end of the airpipe 25 is adapted to close' the opening 26 ofthe casi1'1gf24gso asto pre` vent vthe oil whichflows from the pipe 23A from passingV through the opening. The

fmv

oil supply from the A passage 17. A spring 20 is disposed in the Vontheunder side of the urner 22 isv connectedy tothe fan y3 I` a5 'i pipe 25 is provided with an annular groove 27 adjacent the outer end thereof which*V ing 26 and thereby permit ing 24 to pass through the opening. The groove 27 is curved so it will spray the oil as it passes through the opening 26.

From the foregoing ,description of `the various parts of thereof may be readily understood. I place the support 1 in any convenient place which is adjacent to; the furnace '(not shown) and' dispose the burner 22 in the combustion chamber of the furnace.

the valve 19 by means of a handle 28 so that f canl be moved into alinement with the lopen` the oil in the castheA device, the operation Y y I then regulate Y the oil in passing from the passage 17 into the passage 16 issprayed by the'valve 19. When the device Vis desired to be operated,- the electric motor noid 11, which isl in series therewith, is actuated so as to move the valve 9 downwardly against the tension of the spring 20V and to open the bore 8. The fan 3, which is now rotated by the motor 21, draws the y oil from the pipe- 18 through the passage 21 is startedand the sole- V17, the needle valve 19, the passage 16, the

bore 8, and forces it on through-the pipe 23. As heretofore stated, the oil p-assing through the pipe 23 is in sort of a mist, since it has been effectively broken up by the needle valve 19. The oil passing through the pipe 23 is also provided with the desired amount of air, since the suction created by the fan 3 raises the cover 14 and permits air to enter the bore 7 and to mix with the oil. The oil, which isnow in the form of a spray and which is also mixed with the proper. amount of air, enters the casing 24 and passes through the opening 26 thereof. The groove 27 further aids in spraying the oil vasit passes from the opening 26 and regulates the quantity of oil passing from the opening. An additional amount of air is also provided to the combustion Vchamber of the furnace by'means of the pipe 25 andtherefore complete combustion of the oil in the furnace is assured.

The operation ofthe device can be instantly stopped by merely cutting off the supply 'of electricity to the motor 21. As soon as this is done, the solenoid 11 becomes deenergized and permits the spring 20 to instantly seat. the valve 9. lt will therefore be seen that the oil from the pipe 18 is instantly checked and is prevented from entering the bore 7 or the upper portion of the bore 8. The suction of the fan 3, which continues to operate a certain length of time after the 'source of current has been shut olf from the motor, will now draw ain through the bore 7 and will be prevented from drawing oil into the fan 3, since the valve 9 has instantly cut o` the supply of oil. The oilt is therefore prevented from' entering the fan 3 and wil-l` not become sluggish ,thereiny while the fan 3 is idle. When the device is again started, the fan 3 will not be. hindered from rotation, since there is no oil therein.
